        Relative positioned block size doesnt update root layer size

        - take relative positioning into account in leftmost/rightmost/lowestPosition()
        - ignore zero width/height boxes in leftmost/rightmost/lowestPosition()
        - split relativePositionOffset() to x and y functions
